Anisotropic Interactions between Cold Rydberg Atoms.

摘要

In this project, we have investigated Forster resonance processes in an atomic sample trapped in a CO2 optical dipole trap. The process was investigated as a function of: i) atomic density; ii) dc electric field; iii) and electric field orientation. In the literature, such process has been associated with a many body effect. However, we have obtained experimental and theoretical results which support that the process is dominated by two body interactions. This has been possible thanks to the collaboration with Prof. Shaffer group from University of Oklahoma. Several papers were published, and one workshop was organized in Brazil.
